When you are there, you can also fix the line ending convention of the files. And of course, you'd neet to check the code, because Cuis is not 100% compatible with Squeak. We don't use Monticello in Cuis. At some point in the past it was possible to open MC files in Cuis, but nobody used that feature in ages and it got bitrotten.

Any way to get the Installer available in cuis? Install Monticello config maps?

I got inspired by your proposal, Luciano, and here's my solution in eventual promises. Code can be loaded as: <blockquote> Installer ss project: 'Cryptography'; install: 'ProCrypto.release.3'. </blockquote> I added a test method <blockquote> RefsTest>>#testMultiReturns | selectCount unionFlag pair | unionFlag := false. selectCount := 0. ((pair := self promiseResolverPair) key xgcd: 9) <<* [:each | selectCount := selectCount + 1. Transcript cr; show: 'each = ', each]; <<* [:g :s :t | unionFlag := true. Transcript cr; show: 'g = ', g, '; s = ', s, '; t = ', t. g + s + t]. pair value resolve: 21. (Delay forMilliseconds: 333) wait. self assert: (selectCount == 3). self assert: (unionFlag). </blockquote> This calls new multireturn #xgcd: method <blockquote> xgcd: anInteger " 21 xgcd: 9" | g s t | g := self gcd: anInteger. s := self / g. t := anInteger / g. ^ { g. s. t} </blockquote> And in the test method there are eventual sends (#<<*) to the promise of the #xgcd: send once the reciever promise is resolved to 21. This implementation detects cardinality of the continuation block and sends #whenResolved: appropriately, for future evaluation. <blockquote> Object>>#<<* continuation (continuation numArgs == 1) ifTrue: [^ self whenResolved: [:result | result do: [:each | continuation value: each]]]. ^ self whenResolved: [:result | continuation valueWithArguments: result]. </blockquote> One can see a 1 cardinality schedules the continuation to evaluate with each result, while a continuation with cardinality 2 or more will be scheduled to receive all results. #valueWithArguments: Here are 2 return handlers, <blockquote> promise := ((pair := self promiseResolverPair) key xgcd: 9). </blockquote> the first for each argument <blockquote> promise <<* [:each | selectCount := selectCount + 1. Transcript cr; show: 'each = ', each]; </blockquote> and the second for all three arguments. <blockquote> promise <<* [:g :s :t | unionFlag := true. Transcript cr; show: 'g = ', g, '; s = ', s, '; t = ', t. g + s + t]. </blockquote> <pre class="moz-signature" cols="72">-- ❤️‍🔥🐰 </pre> <div class="moz-cite-prefix">On 6/21/23 09:44, Luciano Notarfrancesco via Cuis-dev wrote: </div> <blockquote type="cite" cite="mid:CAL5GDyrAapan9L5do9F_rM1oEkB_iE9=tfHu-i14ew25fHHH6A@mail.gmail.com"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <div dir="auto">Interesting, thanks for sharing!</div> <div dir="auto">Actually I think it’s the same thing I did, my implementation calls BlockClosure>>#valueWithPossibleArgs: and takes only as many arguments as needed by the block but the array can be bigger than that (it should be named #valueWithPossibleArguments: tho, abbreviations are ugly).</div> <div dir="auto"> </div> <div> <div class="gmail_quote"> <div dir="ltr" class="gmail_attr">On Wed, 21 Jun 2023 at 15:37 Christian Haider via Cuis-dev <<a href="mailto:cuis-dev@lists.cuis.st" moz-do-not-send="true" class="moz-txt-link-freetext">cuis-dev@lists.cuis.st</a>> wrote: </div> <blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div link="#0563C1" vlink="#954F72" style="" lang="DE"> <div class="m_-976565113171439616WordSection1"> I added something similar to my Values package (VW and ports).

Writing methods that return multiple values is easy with the curly brackets syntax, Integer>>#xgcd: ends with something like </div> <div> ^ {g. s. t} </div> <div> But using sending messages that return multiple values is kind of annoying, I end up doing something like: </div> <div> xgcd := a xgcd: b. </div> <div> g := xgcd at: 1. </div> <div> s := xgcd at: 2. </div> <div> t := xgcd at: 3 </div> <div> Some years ago I thought about using blocks for this, but I never tried it. Today I just did a little experiment implementing anArray | aBlock as ‘^ aBlock valueWithPossibleArgs: self’ and I can do: </div> <div> (a xgcd: b) | [:g :s :t| … ] </div> <div> </div> <div> This is seems quite nice already, I guess I’ll start using it and see how it feels. But the point of this mail is not to show a solution, but to ask if anyone have thought about this or if they know any nicer solutions.
